Section $3$: Uncovered Interest Parity $($UIP$)$

Assume that the following rates between the US dollar and the Brazilian real currently exist:

Spot exchange rate: $E_t=$$$\frac{0\mathrm{.}20}{B}$real;

Interest rate on $180-$day US dollar$-$denominated bonds: $i_{t+1}=3\%.$

Investors expect the spot exchange rate in $180$ days to be: $E_{t+1}^e=$$$\frac{0\mathrm{.}18}{?}$ Breal.

Do financial investors forecast a deprecation or an appreciation of the US dollar against the

Brazilian real?

Following the Uncovered Interest Parity $($UIP$),$ what should be the interest rate on $180-$day

Brazilian real$-$denominated bonds $i_{t+1}^{**}?$
